Problem with contact


I have a nc16 up and running, but when i call contact it says there are no contacts i.e. entries, but that is wrong.
Further on, I see no more groups of contacts i.e. familie or friend.

The contacts can all be seen in Thunderbird but not in the web frontend. I can open the list near the settings menu, but no entry can be selected.

Is it possible to repaire the database - I’m quit familar with sql and postgres - but have no idea of the structure i.e. where the groups can be found.

Many thanks for any suggestions

maybe it’s related to this issue on github?
